Local quantum energy conditions in non-Lorentz-invariant quantum field theories

D Grumiller, P Parekh, M Riegler - Physical review letters, 2019 - APS
We provide the first example of local quantum energy conditions in quantum field theories
that are not Lorentz invariant. We focus on field theories in two dimensions with infinite …

Energy density from second shape variations of the von Neumann entropy

S Leichenauer, A Levine, A Shahbazi-Moghaddam - Physical Review D, 2018 - APS
We compute the local second variation of the von Neumann entropy of a region in theories
with a gravity dual. For null variations our formula says that the diagonal part of the quantum …

Quantum null energy condition and its (non) saturation in 2d CFTs
